An open systems approach to quantum optics : lectures by Howard Carmichael

By Howard Carmichael

This quantity includes ten lectures awarded within the sequence ULB Lectures in Nonlinear Optics on the Universite Libre de Bruxelles in the course of the interval October 28 to November four, 1991. a wide a part of the 1st six lectures is taken from fabric ready for a booklet of a little better scope so that it will be published,by Springer lower than the name Quantum Statistical tools in Quantum Optics. The relevant reason behind the early e-book of the current quantity matters the fabric inside the final 4 lectures. the following i've got prepare, in a roughly systematic approach, a few rules concerning the use of stochastic wavefunctions within the idea of open quantum optical structures. those principles have been built with the aid of of my scholars, Murray Wolinsky and Liguang Tian, over a interval of roughly years. they're outfitted on a starting place laid down in a paper written with Surendra Singh, Reeta Vyas, and Perry Rice on waiting-time distributions and wavefunction cave in in resonance fluorescence [Phys. Rev. A, 39, 1200 (1989)]. The ULB lecture notes include my first severe atte~pt to offer an entire account of the information and their strength functions. i'm thankful to Professor Paul Mandel who, via his invitation to offer the lectures, prompted me to arrange whatever necessary out of labor which may, in a different way, have waited significantly longer to be introduced jointly.

Finally, we will consider more physically realistic solutions which have small spatial extent transverse to the propagation direction. A typical example is a Gaussian beam, familiar to anyone who uses a laser pointer. As we will show, we can characterise these by their beam width, w, and radius of curvature, R and thus describe the beams using complex beam parameter (cbp) theory.

This feature of laser light is exploited in the design of optical tweezers, ultimately used to exert forces that can test the mechanical properties of interesting complex fluids. 1 Introduction In 1864, James Clerk Maxwell made the remarkable discovery that light could be described as an electromagnetic wave (Maxwell, 1864) and therefore was governed by the same laws as all other forms of electromagnetic radiation. In particular, as the electromagnetic wave equation is derived from Maxwell’s equations, then any solution to the wave equation must also satisfy Maxwell’s equations.
